I would like to see the persimmon tree.

The issue of free time, versatility, and focusing on something important is simply a matter of one's life goals. It's a complex question, and you can find some truth in both perspectives.
Perhaps a person focuses on reading in their youth and then becomes an outstanding journalist. Or they focus on games and become a top-tier gamer.
Or maybe they don't want to become Bill Gates or Elon Musk (in the sense of being "the best in their field"), but instead focus on work that is useful to people and interesting to them, while diverse entertainment provides them with a fulfilling rest?

The only thing that matters is how you see yourself in this life, how conscious your decisions are, and whether you understand why you need versatility or why you need focus.

But in the end, he still became a "hushnik"... yes, that's harsh.
